Thermal conductivity of two-dimensional group IV-element thermocrystals

A thermocrystal is a type of periodic structure bandgap material that can control heat flux transmission and reflection. In this paper, we use and improve a model based on the kinetic theory of transport processes to calculate the corresponding thermal spectra, dispersion relations and thermal trans...
